Rated 5 out of 5 by from Great washer, especially for the price... The Generac OneWash is a great pressure washer for any use. I've owned this pressure washer for 18 months now, and I have not had a single issue with the machine. The fuel capacity is sufficient to do multiple small jobs before a refill, or large jobs on one tank. A full tank of fuel last me about a month on the random work I complete with it. From washing the house, cars, boat, camper, cleaning the driveway, and other misc. maintenance tasks. The washer usually starts on the first pull of the rope, and is very simple to operate. I have used this machine to strip the finish off of a privacy fence, paint off of a raised deck, and to clean mildew / dirt off of the sides of a house. Each time, the dial to adjust the pressure was perfect, with the included tips, to perfectly match the pressure needed to the job. I couldn't be happier with my purchase.

Rated 4 out of 5 by from I like the variable pressure! The website was very hard to navigate. Machine is very quiet. An O-Ring broke after 5 hours of use.

Rated 4 out of 5 by from Difficult to start Very difficult to start because of kickback even with depressurizing wand. Usually get someone to hold trigger while I start it

Rated 5 out of 5 by from One Wash This pressure washer is just what I was needing. I do like how the engine idles down to a lower RPM to reduce pressure in the system. Gives you more options with pressure and the tips.

Rated 5 out of 5 by from This power washer is the best The One Wash power washer is the best I have ever used. Easy starting, great nozzle selections, 30 foot hose, and a very easy to use nozzle that does not require very much strength to give full washing power, which makes it very easy on the wrist. I have used it on vinyl siding, concrete driveway, sidewalk and on my deck and it is an excellent performer on these surfaces. I would recommend this power washer to anyone.

Rated 5 out of 5 by from First Power Washer Great power washer. The nozels it comes with are good. It's great I can wash my drive to seal it and the dial it down to wash my cars! The hose is 30 feet and works real well. I wish the hose placement was a bit better it tends to touch the engine so i worry it might melt the hose is the only reason for 4 stars.
